Premium Furnace Filters in Calgary: Let's Compare MERV Ratings & Types
We spend many of our hours at home, reading, cooking, taking showers, or just relaxing. Healthy and clean indoor air is a MUST! If the air in your home feels musty and you find yourself with frequent allergies due to dust or pet dander, it's time to invest in quality furnace filters in Calgary and Edmonton.
These top-rated Calgary furnace filters trap airborne particles and allergens, boosting indoor air quality and the efficiency of your HVAC system. However, choosing the right one for your home might be daunting, especially if you don't know what a "MERV" rating is and what to look out for.
Luckily, this in-depth guide covers everything from the 5 most common filter types and their benefits, how to find the ideal filter size for your home and more. You'll also understand MERV ratings, how often you should consider replacements, and where to find the highest-quality furnace filters in Calgary.
Let's begin.

Why Order Furnace Filters in Calgary?
Cold winters and dry summers are common in Calgary. In the winter, we usually turn on the furnace to circulate warm air throughout the house. During summer, there are usually more allergens and dust in the air.
By investing in quality, discount furnace filters, you're making sure that the air in your home stays clean and pollutant-free, thus reducing the risk of respiratory issues and allergies.
Also, think about replacing furnace filters in Calgary, as replacements help keep your HVAC system working like a charm. If you end up with a clogged filter, the furnace will be forced to work harder. As a result, you might have to deal with higher energy consumption and possible system breakdowns.
Essentially, the role of an air filter for a furnace is to remove unwanted particles and many other contaminants from indoor air. Since air flows through the heating system, it also has to go through the furnace filter.
The filter medium, often pleated cloth or fibreglass, captures and traps particles of mould, pollen, dust, and other materials that could potentially reduce the air quality in your home.
What are MERV Furnace Filters?
Before you buy furnace filters in Calgary, you need to understand MERV ratings and what they mean. By doing so, you'll be able to choose your furnace filters in Canada more effectively.
"MERV rating" is short for Minimum Efficiency Reporting Value, and it measures how effectively a furnace filter can trap particles in the air. If the filter has a higher MERV rating, it indicates better filtration. That said, choosing the most appropriate MERV furnace filters will depend on what you need.
-
MERV 8 furnace filters: It's suitable for capturing pollen, dust, and larger particles in the air. These MERV furnace filters are a good choice for most homes without pets or household members who aren't allergy-prone.
-
MERV 11 furnace filters: These trap finer particles, including mould spores and pet dander. Order furnace filters in Calgary and Edmonton, and choose MERV 11 if you have pets or loved ones with mild allergies.
-
MERV 13 furnace filters: Offers the highest residential filtration. These MERV furnace filters remove smoke, fine allergens, and even bacteria. It's the best option for people with allergies and homes in areas prone to high pollution levels.
The most appropriate MERV furnace filters will help balance air quality in your home and make sure your HVAC system is working seamlessly. Keep in mind, though, that higher MERV ratings aren't always the best solution. If the HVAC system isn't designed for it, they may restrict airflow.
Sometimes, a lower MERV rating is better. If you have any questions about Calgary furnace filters and MERV ratings, contact us, and we'll be happy to help!

5 Most Common Furnace Filters: Pros and Cons
The world of furnace filters is versatile, and there are several types you can consider. The most common are fibreglass, pleated, and HEPA filters, but electrostatic and activated carbon are also reasonably popular. Here are the pros and cons of each type so you can choose furnace filters in Calgary more easily!
-
Fibreglass furnace filters: When you order furnace filters in Calgary or Edmonton, you'll probably come across fibreglass types. They're generally affordable, disposable, and provide basic filtration.
Fibreglass furnace filters are useful for a wide variety of homes. However, they aren't as effective as other filter types, and they may require frequent replacements.
-
Pleated filters: Pleated filters are believed to be "superior" to fibreglass. These air filters are made of cotton or polyester material, and they can catch smaller air particles.
On the downside, pleated filters can slightly restrict airflow if they aren't matched correctly with HVAC capacity. They are considered effective and cheap furnace filters.
-
Electrostatic filters: This furnace filter involves an electrostatic charge. It works similarly to a magnet, drawing in and trapping particles. However, it's one of the most expensive options on the market.
-
HEPA filters: Order Calgary furnace filters and choose HEPA(High-Efficiency Particulate Air), as it's the most effective at removing fine particles (a whopping 99.97 percent efficacy) and bacteria. While the price is usually high, these furnace filters work like magic.
-
Activated carbon filters: These furnace filters feature carbon, which can trap particles, odours, and gasses within their pores. These filters are usually preferred for removing unpleasant smells from homes.
Purchase furnace filters in Edmonton and Calgary and breathe in fresh indoor air! Remember, choose high-quality filters from the most suitable material and results are guaranteed. The best air filters for a furnace are just a click away.
